The pipeline will replace existing portable water mains across the North East of England. GPHL are installing over 11 km of new steel welded main, completing works at the Whorley Strategic Connection including three number cast in situ underground tanks and tying in both the new inlet and twin outlet pipework to the existing reservoir. Hydro electric: GPHL have recently completed all the civil engineering works on a pioneering new type of hydro energy generation scheme at Whiteadder Reservoir, East Lothian for Scottish Water as part of its work to reduce carbon emissions. The hydro energy generation scheme is fed by a siphon and is believed to be the first of its type in Europe.  The scheme will enable Scottish Water to generate green energy while accurately controlling the level of the reservoir during seasonal fluctuations in weather. The siphon technology in the project allows Scottish Water to draw water up through the intake and over the top of the dam which then runs down through the siphon, through the hydro turbine, and back to the natural environment. Flood alleviation: GPHL are also currently subcontracted to Volker Stevin on the Flood Risk management Scheme in Appleby, for the Environment Agency. The project involves the installation of a new flood relief pumping station and installation of a new stretch of culvert diverting an existing culvert to the pumping station. A new rising main will outfall into the River Eden. The scheme is known as Appleby Town Centre Flood Risk Management Scheme (FRMS) and aims to reduce flooding caused by surcharging of the Doomgate Culvert which is designated as a main river and is a tributary of the River Eden.

    Nereda logo

    Nereda

    United Kingdom

    Nereda® technology from Royal HaskoningDHV offers sustainable wastewater treatment solutions for municipal and industrial water. The natural sewage treatment process purifies water with minimal or no chemical usage by using the patented aerobic granular sludge technology. Compared to activated sludge technologies, the biological treatment power of the technology is much larger, while saving up to 50% on energy costs, delivering high quality effluent for low costs and requiring only a quarter of the area of conventional activated sludge installations. Biomass in the process develops as fast settling aerobic granular sludge. These granules have excellent settling properties, so the process does not require a separate time-consuming decant phase like conventional SBR’s. All the biological treatment processes take place simultaneously in the granules, requiring only one tank. The technology is very versatile; it can be developed as a new build or used to retrofit existing conventional CAS or SBR plants. The benefits of the technology include: Excellent treatment results and settling properties: Compared to activated sludge technologies, the biological treatment power of the technology is much larger as a considerably higher concentration of biological active mass is applied that in addition has a much higher content of microorganism that are crucial for biological nitrogen and phosphate removal. Sustainable: Compared to conventional wastewater treatment processes, the technology not only has significantly lower energy consumption and associated greenhouse gas emission, but also produces, commonly without the use of waste generating chemicals, a remarkably high effluent quality. Cost effective: The technology results in construction costs that are lower than for conventional technology as for example, tank volumes are up to four times smaller and less equipment is required. Small physical footprint: Its footprint at sewage treatment plants is reduced due to the full nutrient removal process taking place in one single reactor. Easy to operate: It has proved in operation to satisfy the most stringent purification requirements. Thanks to the nature of the technology, plant operation is easy and process performance robust. The technology is proven and applicable for even the largest applications. Currently, there are over 70 wastewater treatment plants in operation or under construction all over the world

    EPC and Design-Build Delivery for Water and Wastewater Treatment Plant Projects

    Water treatment plant construction projects are delivered through several contracting models, each with distinct risk allocation and owner involvement implications. Design-bid-build (DBB) gives the owner maximum design control and allows competitive bidding on construction, but creates interface risk between the designer and contractor and longer overall project timelines. Design-build (DB) transfers both design and construction responsibility to a single entity, reducing interface risk and typically compressing schedule, but requires the owner to define performance requirements clearly in the basis of design before contract award. Engineering, procurement, and construction (EPC) adds procurement responsibility to the contractor scope, appropriate for process-intensive plants where equipment selection is integral to the process guarantee.

    Civil, mechanical, and electrical integration is the primary source of cost overruns and schedule delays in water plant construction. Mechanical equipment submittals that arrive late cascade into concrete foundation delays; electrical raceway conflicts with process piping discovered in the field generate expensive rework. Contractors with in-house design capability in all three disciplines, using a coordinated 3D building information modeling (BIM) workflow, consistently deliver better construction coordination than those who subcontract design and rely on 2D coordination drawings. Ask contractors to describe their clash detection and coordination process during proposal evaluation.

    Commissioning and startup for biological treatment processes—activated sludge, anaerobic digestion, biological nutrient removal—requires significantly more time and process expertise than mechanical equipment startup. Seeding and acclimation of biological cultures to design loads can take 60–120 days, during which the plant may not meet permit limits and a regulatory variance or temporary operating limit may be required. EPC contractors who include a process commissioning team with microbiological and process control expertise as part of their contract scope—not as an owner responsibility—provide substantially better performance milestone accountability.

    Frequently Asked Questions

    What is the difference between a design-build and an EPC contract for water plant construction?

    Design-build contracts combine design and construction under a single contractor responsible for delivering a complete facility meeting the owner's performance requirements. EPC (Engineering, Procurement, and Construction) contracts additionally transfer equipment procurement responsibility to the contractor, who selects, purchases, and is responsible for all major process equipment as part of the lump-sum price. EPC is the appropriate model when the contractor's equipment selection directly determines whether the process performance guarantee is achievable—as is the case for most water and wastewater treatment plants with defined effluent quality requirements.

    How should I structure a process performance guarantee in a water plant construction contract?

    A process performance guarantee should specify: the effluent quality parameters and limits to be met (tied to your regulatory permit or design basis), the influent quality envelope within which the guarantee applies, the test protocol for demonstrating compliance (typically a 30-day performance test at defined flow rates), the financial remedy if the contractor fails the performance test (liquidated damages plus obligation to remediate), and the boundary conditions that would relieve the contractor of guarantee obligation (e.g., influent quality consistently outside the design envelope). Vague guarantees referencing 'best efforts' or 'industry standards' are not enforceable.

    What commissioning milestones should be specified for a new water treatment plant?

    Commissioning milestones should include: mechanical completion (all equipment installed and pre-checked), wet commissioning (system filled, pumps operational, all instrumentation calibrated), cold performance testing (hydraulic and mechanical systems at design flow without process chemistry), chemical system startup (chemical dosing operational and validated), process performance test (effluent quality demonstrated against permit limits over a defined period), and beneficial use acceptance (owner acceptance of the plant for permanent operation). Biological treatment plants require a separate biological startup and acclimation milestone before the effluent quality test can be scheduled.

    How do I evaluate a water plant construction contractor's relevant experience?

    Request a project list filtered to plants of comparable process type (activated sludge vs. physical-chemical vs. membrane), comparable flow rate and capital value, and comparable contractual model (EPC vs. design-build). Visit at least two reference plants and speak directly with both the owner's project manager and the plant operations manager—construction quality and process performance are visible years after project completion, and operators see problems that owners may not surface. Ask specifically about commissioning challenges, change order history, and whether the plant met its permit performance requirements within six months of startup.
